Advancemame users: sync polarity parameter?

<< < (2/3) > >>

tikbalang:
the parameter you are looking for is the modeline created by advcfg.exe or advv.exe. you will still need these two:

device_video_clock
device_video_format

from your monitor specs.

once you test and select working modelines, it will be added into your .rc file. you can force modeline usage with:

display_mode auto | MODELINE_NAME

i don't use this method.

I've thought about all that. In the first part, I get the same scrambled picture when selecting '15khz starndard resolution monitor' in advcfg, so I can't even get a 'format' out of it.

tikbalang:
i forgot to mention that i'm using a pc monitor with advmame. you also have to consider the capabilities of your video card. there was a time i was using an old 4mb s3 virge agp and the video came out as:


--- Code: ---
[ ]]]]]


--- End code ---

or


--- Code: ---
[ ][ ][ ]
[ ][ ][ ]


--- End code ---

where [ ] = one screen. i don't know what kind of error it was but the game screen is multiplied depending on its resolution. i swapped the s3 card with a 2mb ati pci and it worked with no speed losses.

the list of vidcards in the docfiles are outdated. if you want, you can try lincade.

Ummon:
I'm using the Windows version.

Ummon:
Here's a bump. I just can't figure this. I get a stable picture in Windows Mame. But in Advancemame I get a stable, it doesn't roll, yet scrambled picture.
